The organisers of the Commonwealth Games in Delhi are using trained langur monkeys to try and prevent wild animals infesting sporting venues in Delhi.
These highly intelligent primates have been patrolling stadiums and accommodation blocks to scare off other wildlife, including wild monkeys, dogs and snakes. Numerous handlers have been drafted in to patrol the athletes’ village.
Langur monkeys are not only noted for their intelligence but also for their aggression, and this makes them highly effective in deterring other animals from taking up residence.
